Such modes are determined through the solution of a system of two coupled integral equations. An example, for which the modal decomposition is obtained in closed form in terms of fully linearly polarized Hermite Gaussian modes, is given.engjournal articlehttp://dx.doi.org/10.1364/JOSAA.20.000078http://www.opticsinfobase.orgopen access535Hermite-Gaussian ModesLaser-BeamsMultimode LasersLight-BeamsPropagationIntensityFieldQualityPulsesMatrixÓptica (Física)2209.19 Óptica Física
